In a previous blog post about data engineering, we went through several many concepts related to data engineering such as data modeling, and then we went through different types of databases, for example, relational databases and we also got a glimpse of relational as well as NoSQL databases. And in today's blog post we will be writing about data engineer applications. Which are basically the use cases of data engineering 1st let's see what data engineering applications mean; so basically when we have data and we have engineered it then there are several things that we can do with that data and these things that we can do with processed data are the use cases of the data engineering. For example: If we have filled our containers with the data then it's not of any good use if it is not clean and well-formed. If your data is well-formed and if there are no logical mistakes, missing values, and garbage then we can easily perform the use cases and applications of data enginee...

Relational Data Model

-
Image
In the previous blog post, we covered Data Modeling. We have seen that data modeling is really important before jumping into predictive modeling.  In this article, we will cover the Relational Data Model (RDM). Let's start from the very basics, relational means anything which is linked with some other thing. This link is called "Relationship". In RDM or RM there are major three types of relationship cardinalities (also called Multiplicities or Cardianalities): 1. One to one 2. One to many 3. Many to many We can understand these with the help of a few simple examples;  One to one: One department has one manager. One to many: One class has many students. Many to many: Many teachers can teach many students. Okay, so we have got an abstract overview of the term " Relational ", now the next thing is " Data ", data covers everything, anything... And finally, " Model " means something in the form of a template, design, a kind of blueprint.  To store...

See The Pattern : Similarity

-
Image
There are a lot of challenges and issues that demand for similarity measures among the graphs or networks, with the increase in technology the social network is also increasing day by day, therefore there is a need for more speed and more security. When we look at the mutual friends on Facebook, when we browse the internet and find all the related material to our search, or when we go to the doctor for DNA tests, the doctor provides the similarity measures among us and our family members. We wonder that how Amazon, YouTube and other related sites are giving suggestions related to our query. So there comes the concept of Similarity among different things and making clusters of those things that are very much similar.  Network Similarity is a vast field, it enables us to accomplish several mining tasks like visualization, discontinuity detection and clustering. And this require algorithms,  Designing of an algorithm to solve any problem is a big task, after the desig...

There was a question related to <datalist>  regarding HTML 5. Question: Is it necessary to have <input> tag for  <datalist> usage or The search bar in the output is due to the <input> tag? Answer: Yes, the <input> tag is a must before <datalist> tag, this is because if you don't use <input> tag, then there will be no data list in the output. Reference code: (WITHOUT INPUT TAG) <!DOCTYPE html> <html><head><title></title></head> <body> <form action="" method="" > <datalist id= "list" > <option value= "a" > <option value= "b" > <option value= "c" > <option value= "d" > </datalist> </form> </body> </html> Output: Nothing in the output _ blank Do you see anything in the output ?

There discoverers like to discover real pythons and turtles. On the other hand, kids like drawing and coloring them on paper, but programmers are fond of giving commands to computer via python and turtle, and then they make something out of that. Yes, you guessed right! Today we'll have a look at Python Turtle Graphics , so let's begin...

If you are bored of your career choice, and you are thinking that you have made a wrong choice. And now you don't have any other choice but to pursue this career. Then this blog post is for you... Today I watched  a few Motivational videos by Qasim Ali Shah and Sandeep Maheshwari .  The lesson I learned from those videos can be applied in the lives of Software Engineering students or any other person's. Lesson: You have got this life and this is up to you, how you shape this. Currently you might not have any passion in your life. But your live's passion could be that you have to master each and every aspect of your life. Meaning that the things, the issues, a programming problem, a bug in the code, anything that encounters you in your life, you need to tackle with that professionally. See yourself as a Master Piece. Allah has created you, and you are a Master Piece, you are no less. If Software Engineering was once your passion and now you are no more pas...
